Panasonic has also tweaked the hardware's polycarbonate-encased magnesium alloy chassis, with MIL-STD-810G1 ensuring that the gear will survive drops from six-feet, as well as IP651 weather-proofing.
That new hardware is evidently smaller than what it's replacing: though the Pro shares the same size chassis as its predecessor, it packs a 74Wh battery (the older Blade has a 60Wh cell).
